ROLLER SHOPPING BAG Application filed January 20, 1980. Serial .No.422,011.

handles, and it is therefore an object of the invention to provide ashopping bag having 1 flexible walls secured at their lower ends to arigid platform mounted upon wheels, so that the filled or partiallyfilled container may be easily trundled about when in a loadedcondition.

A further feature is in the provision of means whereby the heavilyloaded bag may be guided in a desired direction by the handles, whichare placed at an appropriate height to be readily manoeuvred.

Another aim is to provide a shopping bag having strong but flexiblewalls, capable of conforming to the commodities which may be enteredtherein and resting on the platform or bottom so that no weight need becarried by the hands.

These advantageous objects are accomplished by the novel constructionand arrangement of parts hereinafter described and shown in theaccompanying drawings, forming a material part of this disclosure, and

in which Figure 1 is a side elevational view of an embodiment of thedevice as in operative position.

Figure 2 is an end view of the same.

Figure 3 is a bottom plan View, showing in broken lines-the angularposition which the rear dirigible wheels may assume.

The structure comprises a rigid rectangular plate 10, preferably made ofwood or other stiff material, and secured to the edges of the plate arethe side and end walls 11 of the bag, these walls being made preferablyof oilcloth, canvas or other strong but flexible woven textile fabric.

. Centrally of the sides and at their top ,edi'esra're a pair of stronghandles 12 shaped to e conveniently grasped and the terminals 13 of thehandles are extended outwardly on both side edges the full length of thebag, the materialof which is seamed to enclose the elements 13 in asecure manner, affording a finished appearance and re-enforcing theedges.

Secured transversely on the under side of the platform 10, near itsfront end, is a bracket 14 held by bolts 15, the downreaching ends ofthe bracket having fixed therein pintles 16 to which are secured, byscrews 17, a pair of wheels 18, washers being provided between the headsof the screws and the shoulders of the pintle, so that the wheels willreadily revolve.

These wheels are preferably of a considerable diameter equallingapproximately the width of the platform 10, and are positioned to avoidas far as possible tipping or overturning of the structure.

Centrally of the platform 10, and at a point near its'opposite end, is apost 19,.rigidly supported by clamp nuts 20 above and below the plateand journalled on the post, between suitable washers, are a pair ofspaced lugs 21 formed on a yoke-like member 22, the diverging elementsof which at their outer endsare bent parallel and suited to receive asecond pair of pintles 23 on which the rear wheels 24 are rotatablymounted, being held in position by screws 25.

llhe rear or trailing wheels 24 are spaced in a similar mannerto thefront wheels 18, and obviously by their attachment to the yoke 22 may beturned as a unit on the axis of the post 19, the turning movement beinglimited by a stud 26 fixed in the platform to extend downwardly betweenthe yoke members ,whereby the wheels are held at all times in operativeposition.

It will be apparent that a similar structure may be used in connectionwith trunks, valises, suitcases, tool boxes, and other like containersordinarily conveyed by hand, and that the same can be manipulatedthrough traflic-without resorting to unecessary lifting.

Furthermore the four wheel arrangement 2 neaaeea I provides a wide base,tending to revent the ag from toppling over, while t e material 1 of thebag sides is such as to yield and readily receive articles ofconsiderable size and of any shape within its capacity, the bag bulgingin conformity.

The bag is under complete control of the handles 12, which in useapproach each other closely, and by means of which the rear wheels areeasily steered.

From the foregoing it will be seen that a simple device for this purposehas been disclosed in the preferred form of its embodiment, but it isnot desired to restrict the de-= tails to the exact construction shown,it be ing obvious that changes, not involving the exercise of invention,may be made without v conflicting with the scope of the appended' claim.

Having thus described the invention, what is claimed as new and desiredto secure by Letters Patent, is 2-- A portable container having a rigidbase, airs of wheels at the front and rear of said ase, said frontwheels having fixed transverse axes and said rear wheels beingdirigible, all of said wheels being alike in diameter and each said pairequally spaced a art, means to limit the angular movement 0 thedirigible wheels, all of said wheels being within the planes of the baseedges and adjacent thereto, and a pair of normally spaced apart rigidhandles on the sides of the container by which it is ided and supported,said handle having eng extensions embedded in the upper edges of thecontainer side walls. In testimony whereof I aifix my signature.
